EIA/TIA 568 standard A
a standard for building cable for commercial buildings that support data networks, voice and audio
corssover EIA/TIA 568 A and B cables
directly connects two computing devices or two switches together
What is a cable plan and why would you want one?
documentation and paperwork that shows where and what each cable is and what it does. Good for futrue reference and organization
why use a patch panel
it will help keep it organized as well as make it easier to move, add, or change cabling infrastructure
EIA/TIA 568 standard B
no different from 568 A but green and organe wire are switched
EIA/TIA 568 standard B twisted pari order from left ot right
orange/white, orange, green/white, blue, blue/white, green, brown/white, brown
physical media
physcial meaterial used to transmit information in data communications, normally in the form of copper or glass
improper cabling can lead to....
speed loss, irregular network cable issues, and poor data transmission
strippers
strip cabling of csing
TIA 530 A
supports balanced and unbalanced trnasmission rates
punch down tool(impact tool)
terminate the wire
TIA 232 F
Serial port not taken over by usbs and ethernets
patch panel
a device or unit featuring a number of jack, usually same or similar type, for the use of connectin gan routing circuits for monitioring, interconnecting, and testing circuits in a convienient, flexible manner
loop-back EIA/TIA 568 A and B cables
a plug used to test physical ports to identify network issues
roll-over EIA/TIA 568 A and B cables
conenct the workstation to the console port of the switch
EIA/TIA 568 standard C
covers systems/components, topology and transmission medium specs, and testing for fiber, twisted pair and coax
where should labels be applied on a cable?
each cable and each pathway on each end, the termination points on both ends of the cable, all jack, connectors and block hardware on either the outlet or panel
RJ45 crimper
form a physical bond of cables
EIA/TIA 568 standard A twisted pair order from left to right
green/white, green, green/orange, blue, blue/white, orange, brown/white, brown
shielded cables
reduces electrical noise and protects wires in the cable but hey are expensive and take more time
unshielded cables
they are more hazardous but they are cheaper and take less time
should labeling match the project drawing?
yes, labeling should be logical and consisen, across all locations, mathching the project drawings
